Magpul PMAG D-50 7.62X51 LRSR AR-10 Drum Magazine

Known for their legendary P-MAG magazines, Magpul Industries continues to innovate with the P-MAG D-50 .308/7.62×51 Drum Magazine. Compatible with AR-10s and other firearms that use AR-10 magazines, this drum magazine eliminates the need to constantly reload your rifle by carrying 50 rounds of .308 or 7.62×51. Made with the same standards as the famous P-MAG and .223/5.56 D-60 drum magazines, the D-60 is perfect for expanding your AR-10 rifle’s capacity.

Reliable in function and durable in construction, the D-50 surpasses military dust and debris resistance standards with stoppages only occurring once every 50,000 rounds on full-auto in the worst of conditions and environments. The Magpul PMAG D-50 also incorporates proven GEN M3 technology, which includes next-generation impact and crush-resistant polymer construction and the ability to seat fully loaded on a closed bolt. Robust stainless-steel internals withstand corrosion and long-term storage. It includes a semi-rigid dust cover that prevents grit and debris intrusion during storage and transport.

Additionally, a translucent window on the back of the drum gives a quick visual indicator to the user how much ammo they have left. The D-60 magazine is also easily maintainable with all assembly and disassembly being able to be done with a simple flathead screwdriver.

At the same height as a 25-round .308/7.62×51 P-MAG magazine, this drum magazine won’t hinder the shooter from shooting off a bench or in the prone. The D-50 is also the lightest in its class at 1.7 lbs empty and 4.5 lbs fully loaded without compromising reliability or capacity. The Magpul Industries D-50 Drum Magazine exceeds in all categories needed for a wide variety of uses such as competition shooting, tactical use, and for the prepared citizen. Get the best .308/7.62×51 AR-10 drum magazine available and don’t look back.
